Don't ever send "STORE FLAGS.SILENT ()" since Cyrus imapd doesn't like

2001-08-16  Jeffrey Stedfast  <fejj@ximian.com>

	* providers/imap/camel-imap-folder.c (imap_sync_online): Don't
	ever send "STORE FLAGS.SILENT ()" since Cyrus imapd doesn't like
	this (and maybe others too?) so what we'll do instead is to send
	"STORE -FLAGS.SILENT (\Seen \Answered \Deleted \Marked)" to clear
	all the flags (since this is in essence what we want to do
	anyway).
